Stratovolcano and Associated Volcanic Hazards

The historically active volcanoes in Cook Inlet are stratovolcanoes. These are steep-sided mountains of many layers of lava, ash, and pyroclastic flows produced from a single vent or a few closely-spaced vents. Pyroclastic flows are a mixture of hot gases and fragmented lava. They roar down the flanks of a volcano at 100-150 miles per hour, then harden to form the volcano's outer crust.
